Battery Backed Clock and RAM
The controller includes a real-time clock/calendar and RAM storage for user variables. Both the clock and the
RAM storage require a battery to continue running and for the stored data not to be lost while the controller is
powered down. The battery is not installed by Roboteq. Users who wish to use the clock and/or battery backed
RAM variables must install a battery themselves. The battery socket can be reached by removing the screws
that are holding the cover. Lift the cover to reach the board and insert a 3V, 12.5mm coin-style battery. Use bat-
tery type CR1225 or equivalent.
Measured Amps
The controller includes Amps sensors in line with the motor terminals and on the battery ground terminal. Both
Motor Amps and Battery Amps are therefore measured with precision.
Electrical Specifications
Absolute Maximum Values
The values in Table 6, below, should never be exceeded. Permanent damage to the controller can result.
